Building 3rd-party libraries on Linux

@tableofcontents

@section dev_guides__building_3rdparty_linux_1 Introduction

This document presents additional guidelines for building third-party products used by Open CASCADE Technology and samples on Linux platform.

The links for downloading the third-party products are available on the web site of OPEN CASCADE SAS at http://www.opencascade.org/getocc/require/.

There are two types of third-party products, which are necessary to build OCCT:

  • Mandatory products: Tcl 8.5, Tk 8.5, FreeType 2.4.10
  • Optional products: TBB 3.x or 4.x, gl2ps 1.3.5, FreeImage 3.14.1

@section dev_guides__building_3rdparty_linux_2 Building Mandatory Third-party Products

@subsection dev_guides__building_3rdparty_linux_2_1 Tcl/Tk 8.5

Tcl/Tk is required for DRAW test harness. Version 8.5 or 8.6 can be used with OCCT.

@subsubsection dev_guides__building_3rdparty_linux_2_1_1 Installation from binaries

It is possible to download ready-to-install binaries from http://www.activestate.com/activetcl/downloads

    1. Download the binaries archive and unpack them to some TCL_SRC_DIR.
    1. Enter the directory TCL_SRC_DIR.

@verbatim cd TCL_SRC_DIR @endverbatim

    1. Run the install command

@verbatim install.sh @endverbatim

and follow instructions.

@subsubsection dev_guides__building_3rdparty_linux_2_1_2 Installation from sources: Tcl 8.5

Download the necessary archive from http://www.tcl.tk/software/tcltk/download.html and unpack it.

    1. Enter the unix sub-directory of the directory where the source files of Tcl are located (TCL_SRC_DIR).

@verbatim cd TCL_SRC_DIR/unix
@endverbatim

    1. Run the configure command

@verbatim configure --enable-gcc --enable-shared --enable-threads --prefix=TCL_INSTALL_DIR
@endverbatim

For a 64 bit platform also add --enable-64bit option to the command line.

    1. If the configure command has finished successfully, start the building process

@verbatim make
@endverbatim

    1. If building is finished successfully, start the installation of Tcl. All binary and service files of the product will be copied to the directory defined by TCL_INSTALL_DIR

@verbatim make install
@endverbatim

@subsubsection dev_guides__building_3rdparty_linux_2_1_3 Installation from sources: Tk 8.5

Download the necessary archive from http://www.tcl.tk/software/tcltk/download.html and unpack it.

    1. Enter the unix sub-directory of the directory where the source files of Tk are located (TK_SRC_DIR).

@verbatim cd TK_SRC_DIR/unix
@endverbatim

    1. Run the configure command, where TCL_LIB_DIR is TCL_INSTALL_DIR/lib

@verbatim configure --enable-gcc --enable-shared --enable-threads --with-tcl=TCL_LIB_DIR --prefix=TK_INSTALL_DIR
@endverbatim

where TCL_LIB_DIR is TCL_INSTALL_DIR/lib

For a 64 bit platform also add --enable-64bit option to the command line.

    1. If the configure command has finished successfully, start the building process

@verbatim make
@endverbatim

    1. If building has finished successfully, start the installation of Tk. All binary and service files of the product will be copied to the directory defined by TK_INSTALL_DIR (usually TK_INSTALL_DIR is TCL_INSTALL_DIR)

@verbatim make install
@endverbatim

@subsection dev_guides__building_3rdparty_linux_2_2 FreeType 2.4.10

FreeType is required for display of text in 3D viewer. Download the necessary archive from http://sourceforge.net/projects/freetype/files/ and unpack it.

    1. Enter the directory where the source files of FreeType are located (FREETYPE_SRC_DIR).

@verbatim cd FREETYPE_SRC_DIR
@endverbatim

    1. Run the configure command

@verbatim configure --prefix=FREETYPE_INSTALL_DIR
@endverbatim

For a 64 bit platform also add CFLAGS='-m64 -fPIC' CPPFLAGS='-m64 -fPIC' option to the command line.

    1. If the configure command has finished successfully, start the building process

@verbatim make
@endverbatim

    1. If building has finished successfully, start the installation of FreeType. All binary and service files of the product will be copied to the directory defined by FREETYPE_INSTALL_DIR

@verbatim make install
@endverbatim

@section dev_guides__building_3rdparty_linux_3 Building Optional Third-party Products

@subsection dev_guides__building_3rdparty_linux_3_1 TBB 3.x or 4.x

This third-party product is installed with binaries from the archive that can be downloaded from http://threadingbuildingblocks.org. Go to "Downloads page", find the release version you need (e.g. tbb30_018oss) and pick the archive for Linux platform. To install, unpack the downloaded archive of TBB 3.0 product (tbb30_018oss_lin.tgz).

@subsection dev_guides__building_3rdparty_linux_3_2 gl2ps 1.3.5

Download the necessary archive from http://geuz.org/gl2ps/ and unpack it.

    1. Install or build cmake product from source file.
    1. Start cmake in GUI mode with the directory where the source files of gl2ps are located: @verbatim ccmake GL2PS_SRC_DIR
      @endverbatim
    • 2.1. Press [c] to make the initial configuration
    • 2.2. Define the necessary options CMAKE_INSTALL_PREFIX
    • 2.3. Press [c] to make the final configuration
    • 2.4. Press [g] to generate Makefile and exit

or just run the following command:

@verbatim cmake –DCMAKE_INSTALL_PREFIX=GL2PS_INSTALL_DIR –DCMAKE_BUILD_TYPE=Release
@endverbatim

    1. Start building of gl2ps

@verbatim make
@endverbatim

    1. Start the installation of gl2ps. Binaries will be installed according to the CMAKE_INSTALL_PREFIX option

@verbatim make install
@endverbatim

@subsection dev_guides__building_3rdparty_linux_3_3 FreeImage 3.14.1

Download the necessary archive from http://sourceforge.net/projects/freeimage/files/Source%20Distribution/ and unpack it. The directory with unpacked sources is further referred to as FREEIMAGE_SRC_DIR.

    1. Modify FREEIMAGE_SRC_DIR/Source/OpenEXR/Imath/ImathMatrix.h: In line 60 insert the following:

@verbatim #include string.h
@endverbatim

    1. Enter the directory where the source files of FreeImage are located (FREEIMAGE_SRC_DIR).

@verbatim cd FREEIMAGE_SRC_DIR
@endverbatim

    1. Run the building process

@verbatim make
@endverbatim

    1. Run the installation process
    • 4.1. If you have permissions to write to /usr/include and /usr/lib directories then run the following command: @verbatim make install
      @endverbatim
    • 4.2. If you don’t have permissions to write to /usr/include and /usr/lib directories then you need to modify the file FREEIMAGE_SRC_DIR/Makefile.gnu:

Change lines 7-9 from:

@verbatim DESTDIR ?= /
INCDIR ?= $(DESTDIR)/usr/include
INSTALLDIR ?= $(DESTDIR)/usr/lib
@endverbatim

to:

@verbatim DESTDIR ?= $(DESTDIR)
INCDIR ?= $(DESTDIR)/include
INSTALLDIR ?= $(DESTDIR)/lib
@endverbatim

Change lines 65-67 from:

@verbatim install -m 644 -o root -g root $(HEADER) $(INCDIR)
install -m 644 -o root -g root $(STATICLIB) $(INSTALLDIR)
install -m 755 -o root -g root $(SHAREDLIB) $(INSTALLDIR)
@endverbatim

to:

@verbatim install -m 755 $(HEADER) $(INCDIR)
install -m 755 $(STATICLIB) $(INSTALLDIR)
install -m 755 $(SHAREDLIB) $(INSTALLDIR) @endverbatim

Change line 70 from: 

@verbatim ldconfig @endverbatim

to:

@verbatim #ldconfig
@endverbatim

Then run the installation process by the following command:

@verbatim make DESTDIR=FREEIMAGE_INSTALL_DIR install
@endverbatim

    1. Clean the temporary files

@verbatim make clean
@endverbatim

@section dev_guides__building_3rdparty_linux_4 Installation From Official Repositories

@subsection dev_guides__building_3rdparty_linux_4_1 Debian-based distributives

All 3rd-party products required for building of OCCT could be installed from official repositories. You may install them from console using apt-get utility:

@verbatim sudo apt-get install \
tcllib tklib tcl-dev tk-dev \
libfreetype-dev \
libxt-dev libxmu-dev \
libgl1-mesa-dev \
libfreeimage-dev \
libtbb-dev \
libgl2ps-dev
@endverbatim

To launch WOK-prebuilt binaries you need install C shell and 32-bit libraries on x86_64 distributives:

@verbatim sudo apt-get install \
csh \
libstdc++5:i386 libxt6:i386
@endverbatim

Any compliant C++ compiler is required for building anyway:

@verbatim sudo apt-get install \
g++ \
@endverbatim
